Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Check harness between combination meter and fuse.

3.

CHECK GROUND CIRCUIT

1. Turn ignition switch OFF.

2. Check continuity between combination meter harness connector M24 terminals 21, 22, 23 and ground.

Is the inspection result normal?

YES

>> INSPECTION END

NO

>> Repair harness or connector.

FUEL LEVEL SENSOR SIGNAL CIRCUIT

FUEL LEVEL SENSOR SIGNAL CIRCUIT

Description

INFOID:0000000009266603

The fuel level sensor unit and fuel pump detects the approximate fuel level in the fuel tank and transmits the

fuel level signal to the combination meter.

Component Function Check

INFOID:0000000009266604

1.

COMBINATION METER INPUT SIGNAL

1. Select METER/M&A on CONSULT.

2. Using FUEL METER of DATA MONITOR, compare the DATA MONITOR value with the fuel gauge posi-

tion.

Does monitor value match fuel gauge reading?

YES

>> Inspection End.

NO

>> Replace combination meter. Refer to 

MWI-53, "Removal and Installation"

.

Diagnosis Procedure

INFOID:0000000009266605

Regarding Wiring Diagram information, refer to 

MWI-27, "Wiring Diagram"

.

1.

CHECK HARNESS CONNECTOR

1. Turn ignition switch OFF.

2. Check combination meter and fuel level sensor unit terminals (meter-side and harness-side) for poor con-

nection.

Is the inspection result normal?

YES

>> GO TO 2

NO

>> Repair or replace terminals or connectors.

2.

CHECK FUEL LEVEL SENSOR UNIT CIRCUIT

1. Disconnect combination meter harness connector M24 and fuel level sensor unit and fuel pump harness

connector B44.

2. Check continuity between combination meter harness connector M24 terminal 4 and fuel level sensor unit

and fuel pump harness connector B44 terminal 2.

3. Check continuity between fuel level sensor unit and fuel pump harness connector B44 terminal 2 and

ground.

Is the inspection result normal?

YES

>> GO TO 3

NO

>> Repair harness or connector.
